The bad news: Now there’s evidence that stress can increase your risk of cancer.
In a study published in the April 16 online issue of the Proceedings of the National Academy of Sciences, mice that were restrained (a huge stressor) and then exposed to radiation developed more tumors than unrestrained mice that were exposed to radiation.
